Product Description
Product Overview

The VW-1 Cable Vertical Combustion Test Machine is a precision instrument designed to evaluate flame retardancy properties of wires, cables, electrical accessories, and solid materials. This equipment simulates material burning behavior, flame spread, and self-extinguishing characteristics when exposed to controlled flame conditions.

VW-1 Rating: This designation from UL standards (Vertical Wire-1) represents one of the most stringent flame retardancy classifications for cable products.
Testing Methodology

The instrument secures samples at specified angles (20° or 90° vertical) and applies a standardized flame for precise durations. Key measurement parameters include:

  • Afterflame Time: Duration sample continues burning after flame removal
  • Afterglow Time: Duration sample remains hot after flame extinguishment
  • Charred Length: Maximum burned or damaged sample length
  • Cotton Bedding Ignition: Assessment of flame drippings on absorbent cotton pads
